`WILLIAM M. KEPLER, OF CINCINNATI, OHIO.

IMPROVEMENT IN FIRE-PLACES.

Specification forming part of Letters Patent No. 142.241, dated August 26, 1873 application led May 7, 1873.

To all whom it may concern.l`

Be it known that I, WILLIAM M. KEPLER, of Cincinnati, Hamilton county, State of Ohio, have inventeda certain new and useful Improvement in Fire-Places, of Which the following is a specification:

My invention relates to the class of' replaces having air-heating chambers back of theVfuel-chamber for the supply of heated air to assist in Warming the room the fire is in, or `the -supply of heated air for conveyance to backs; second, in a peculiar construction of top plate for the heating-chamber, which not only serves to hold the corrugated fire-back in place, but enables the top plate to be reversed in position, so as to present the side exit-pipe for the hot air, either upon the right or left side of the lire-place. y

Figure l is a vertical section of a-ire-pla'ce embodying my invention. Fig. 2 is a perspective view of the corrugated fire-back with its reversible top plate.

A is the air-heatin g chamber, and B the lirechamber. They are separated by the lire-chamberback C, Which is of the following peculiar construction: It is formed with a series of corrugations horizontally arranged, each corruga. tion having a front face, c, to radiate heat'directly into the room and into the air-heating chamber, and also a horizontally-located face, c', which acts to catch or arrest the risingV gases from the lire, and formreverberating eddies in the corrugations `to such extent that the fireback is eectively heated, the air in the airchamber'heated by direct horizontal heatingsurface principally, and the combustion in the fire-chamber (by reason of the high temperature of the fire-back and the reverberatory action) materially perfected. The overhanging character of the fire-back C is preferred by me, as it affords, as shown, a favorable ooniiguration for the arrangement of my peculiar form of corrugations. The top plate D of the air-heating chamber is provided at the side With the exit-pipe E for the conduction of hot Y air, and is constructed With grooved ends d d, to fit over the top edge of the nre-back, and hold the latter in place. The back end of the top plate is built inthe brick-Work, as shown. The plate D is grooved both at its front and back edge, as shown at d d', so that in setting up the fire-place either ed ge may be set in front over the top edge of the lire-back, in v`order to locate the pipe E on the side most favorable for the conveyance of the heated air from the fire-place. Pipe or line F supplies the cold airV set my hand.
